How to Change the Diablo2 CD Key

Blizzard developed Diablo 2 for the PC.

Released on June 29, 2000, Blizzard's Diablo 2 continues to be a popular multiplayer game on the game developer's Battle.net server. An action role-playing game (RPG), Diablo 2 is available as part of the Diablo 2 Battlechest edition, which includes the Diablo 2 expansion pack, Lord of Destruction, and the Diablo 2 Official Strategy Guide. In order to play Diablo 2, each game installation requires a unique CD key. You cannot install or play the game without a valid product key.
